We get bored with the same thing after a period of time because the novelty wears off. Hedonic adaptation is the term used to describe how things decrease in their ability to stimulate us over time. A strategy for a satisfied life must include being stimulated with a certain amount of novelty in order to be satisfied. Without, it the core of our sense of satisfaction begins to fade and trouble can arise out of that dissatisfaction.
Some of us are not socialized in such a way that we understand and behave in ways that satisfy our hunger for stimulation constructively. We may crave novelty but not recognize how to respond constructively to that hunger. We might expect others to stimulate us and blame and be disappointed in them when they do not feed our need for stimulation. Some of us destructively attempt to satisfy it by clawing at the fabric of our social environment – perhaps causing drama or reacting to drama. (which is basically the tic and tock of the same drama clock) Still others of us may risk danger and or lifestyle stability just because we’re bored and don’t recognize how to feed our innate need for stimulation.
We can also get caught in a destructive spiral of demands for increasing need for stimulation. Addiction is one form of an over stimulation spiral where an increasing spiral of hunger for stimulation can hijack our capacity to function. In these cases our lives become unstable and spin out of control. If we condense too much rapid change (novelty) into our routine we eventually may be unable to satisfy our own hunger for stimulation and cause a corresponding chaos and depression. The bottom line: It’s important to have a routine, but it’s also important to break it once in a while.
